Colloquium

Dark Matter in the Smallest Galaxies

Speaker:Matt Walker, Carnegie Mellon

Date:March 28, 2018

Time:4:15 pm

Location:Pupin 428

Host:Kathryn Johnston

The Milky Way's dwarf-galactic satellites include the nearest, smallest, darkest
and most chemically primitive galaxies known. I will summarize recent results --
and present new ones -- regarding the amount and spatial distribution of dark
matter within these systems. I will discuss implications for two lines of inquiry
regarding the nature of dark matter: 1) tests of the standard 'cold dark matter'
model of cosmic structure formation, and 2) searches for dark matter
annihilation/decay signals.
